First part of a 3 part wrap up to April's Planetary Defense Conference: a very brief review of the status of research in asteroid threat related fields based on the conference, report on special activities at the conference, and links to video and audio related to the conference.
Partnering with our friends from The Planetary Society, the Space Generation Advisory Council (SGAC), whose members hail from all over the globe, is bringing you an update on our activities and something you can join in on—at least if you are a student or young professional aged 18–35.
Bruce Betts, Mat Kaplan, and asteroid tracker Robert Holmes on the Planetary Society Weekly Google Hangout. Mat discussed and showed pictures from his trip to the giant ALMA observatory and we'll be joined by asteroid tracker extraordinaire, Robert Holmes.
Mostly the Universe stays unchanged for hundreds, thousands or even millions of years. There are some cases however when some things change really rapidly. Recently I observed one of these rapidly changing, transient phenomena, as asteroid called 2012 DA14. I work for Las Cumbres Observatory and we have been trying to observe this asteroid since 5 February.
Continuing my writeup of notes from last week's Division for Planetary Sciences meeting: presentations on the risks of future asteroid impacts. How much risk do we face, and what are the appropriate actions to take in the face of that risk?
A new installment of our "Snapshots" video series examines the threat posed by asteroids on collision courses with our home planet. Emily Lakdawalla explains why it's so important to find, understand and learn to deflect these potential civilization enders.
One nice thing about the Planetary Defense conference is that I not only get to talk with the NEO community of experts all in one place and hear their new science, but I also get updates on projects the Planetary Society has funded.
Meteorites hit Earth all the time, but they almost never score direct hits on human-built structures (or humans, for that matter). Once in a while, though, direct hits do happen, and it looks like this recent event in Poland was the real thing.
